L6474PDTR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The current sense resistors (R Sense) should be chosen based on the maximum current rating of the motor and the desired current sense threshold. A good starting point is to use a 0.1 ohm resistor for a 2A motor and adjust from there.
  • The ENN pin is an active-low enable input that allows the user to enable or disable the driver. When ENN is low, the driver is enabled, and when ENN is high, the driver is disabled. This pin can be used to implement a shutdown or standby mode.
  • To configure the L6474PDTR for microstepping mode, the M1 and M2 pins should be connected to a microcontroller or a dedicated microstepping controller. The microcontroller or controller should send the appropriate step and direction signals to the L6474PDTR.
  • The maximum frequency of the step signal that the L6474PDTR can handle is 100 kHz. However, the actual frequency limit may be lower depending on the specific application and motor characteristics.
